 Thanks for describing the problem so precisely, I can easily see it as
well. And while I didn't have time to rebuild LMI to test it, I think I
might know what is causing it: it may be due to SetDocumentSaved(true) call
in MakeNewIllustrationDocAndView() in illustration_view.cpp. This basically
tricks the document into thinking that it had already been saved even
though it wasn't. And "Save" is intentionally disabled when the document
had been already saved and not modified since -- there is no reason to save
it once again in this case, is there?

 Maybe I'm wrong as this seems to be done for the "phantom" document and
not the real one but this seems like the most likely explanation for now.
I'll try to really debug it a.s.a.p. In the meanwhile I have a question for
Greg: do you know/remember why was this call needed?

 Thanks for your bug report,
